Best ResponseYou've already chosen the best response.0So lets think about what these things mean... Are you familiar with amplitude?

Best ResponseYou've already chosen the best response.0OK, Amplitude is how much to 'amplify' the function by.

Best ResponseYou've already chosen the best response.0If you have 5Sin(x) then its amplitude is 5 (the wave will hit a maximum of 5 and a minimum of 5.

Best ResponseYou've already chosen the best response.0So hopefully that explains amplitude. The period is the length of a wave before it starts repeating itself. The usual period of a sine function is 2Pi as the wave will begin to repeat after that point in time. I.e. period of Sin(x) is 2Pi. Is this making sense so far?

Best ResponseYou've already chosen the best response.0yep, thats right, 7 sin x (for the amplitude part)

Best ResponseYou've already chosen the best response.0\[y(x)=A\sin(\omega t+\phi)+b\] \(A\) is the Amplitude \(\omega\) is the angular frequency \(\frac{\omega}{2\pi}=\)frequency of oscillation \(\tau\) is the period and \(\tau=\frac{2\pi}{\omega}\) \(\phi\) is the phase shift \(b\) is the vertical shift

Best ResponseYou've already chosen the best response.0You are best of taking a look at http://www.intmath.com/trigonometricgraphs/trigographintro.php. This will explain it properly.
